It is configured in.

<Characteristic configuration>
Next, the characteristic configuration of the bathroom heater / dryer A provided with the bath mist device according to this embodiment will be described.

First, in the bathroom dryer with mist function (bathroom heater / dryer) A according to this embodiment, when the bathroom is heated, the temperature in the bathroom 2 is changed by the bathroom heating from the heat source machine 16 which also serves as the hot water supply means in the present invention. The point controlled by the temperature of the supplied hot water for mist will be described.

In the bath mist device of this embodiment, as described above, the hot air heat exchanger 13, the circulation fan 14a, and the like constitute the bathroom heating unit, and the heating hot water supplied from the heat source unit 16 is formed. The air sucked from the bathroom 2 is heated by the heat exchanger 13 for hot air by the flow, and is blown out into the bathroom 2 to heat the bathroom 2.

In the bathroom heater / dryer A of this embodiment, the hot water supply means (heat source machine) 16 includes a mist hot water temperature setting unit that sets the temperature of the hot water to be supplied, that is, the temperature of the mist hot water.

When the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is higher than the temperature detected by the mist temperature thermistor (hot water temperature detection unit for mist) TH1, the control unit B is the hot water for heating in the present invention. The thermal valve 17, which is a flow control unit, is controlled to block the flow of the heating hot water flowing through the heating hot water pipeline 15.

Further, when the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is lower than the temperature detected by the mist temperature thermistor (hot water temperature detection unit for mist) TH1, the control unit B has the heating in the present invention. The thermal valve 17 which is a hot water flow control unit for heating is controlled to maintain the flow of hot water for heating through the hot water pipeline 15 for heating.

Since the temperature of the hot water flowing through the hot water pipeline 15 for heating is usually set to about 70 ° C. to 80 ° C., the control unit B controls the thermal valve 17 to pass through the hot water pipeline 15 for heating. When the flow of hot water for heating is maintained, the air sucked from the bathroom 2 is heated by the hot air heat exchanger 13, the temperature of the air sucked from the bathroom 2 rises, and the air is returned to the bathroom 2. Is done.

Further, when the control unit B controls the thermal valve 17 to block the flow of the hot water for heating flowing through the hot water pipe line 15 for heating, the air sucked from the bathroom 2 is a heat exchanger for hot air. It is not heated by 13, and the temperature of the air sucked from the bathroom 2 does not rise and is returned to the bathroom 2.

If the air sucked from the bathroom 2 is not heated by the hot air heat exchanger 13 and is returned to the bathroom 2 as it is (without the temperature rising), heat is dissipated to the outside in the bathroom 2. As a result, the temperature inside the bathroom 2 will decrease.

Therefore,
(A) Control when the temperature detected by the bathroom temperature thermistor TH3 (the temperature of the air sucked from the bathroom) is higher than the temperature detected by the mist temperature thermistor (hot water temperature detector for mist) TH1 when the bathroom heating is executed. Part B controls the thermal valve 17 to block the flow of the heating hot water flowing through the heating hot water pipeline 15.
(B) Further, when the temperature detected by the bathroom temperature thermista TH3 (the temperature of the air sucked from the bathroom) is lower than the temperature detected by the mist temperature thermista TH1 (hot water temperature detection unit for mist), the control unit B heats up. By controlling the valve 17 to maintain the flow of the hot water for heating through the hot water pipeline 15 for heating, the temperature in the bathroom 2 is adjusted to the hot water for mist supplied from the hot water supply means (heat source machine) 16. Will be controlled by the temperature of.

The bathroom heater / dryer A according to this embodiment configured as described above does not require a liquid heat exchanger, so that the manufacturing cost can be reduced, and moreover, complicated control is not required. The temperature of the bathroom can be easily controlled.

That is, the temperature of the hot water for mist supplied from the hot water supply means (heat source machine) 16 is set to the temperature set by the hot water temperature setting unit for mist, and the temperature of the air sucked from the bathroom becomes the temperature of the hot water for mist. Since the flow of hot water for heating is controlled in this way, it is possible to easily control the temperature of the bathroom so that it becomes the temperature set by the hot water temperature setting unit for mist that the hot water supply means (heat source machine) 16 originally has. It is possible to provide a bath mist device (equipped with a bathroom heater / dryer) having a simple configuration without requiring a separate bathroom temperature setting unit for setting the bathroom temperature.

Further, as described above, the instruction manual states that "the temperature of the bathroom is maintained at the set temperature in the hot water temperature setting unit for mist provided by the hot water supply means", that is, "in the case of performing bathroom heating, bathroom heating The desired heating temperature (heating set temperature) can be specified as the hot water output set temperature of the hot water supply means (heat source machine) 16 ", so that the user can use the heat source machine 16 that also serves as the hot water supply means. Since the hot water supply temperature in the heat source machine 16 is set after recognizing that the set temperature becomes the heating set temperature, the configuration is simple and the bath mist device (equipped with an easy-to-use bath mist device) is provided. Machine) can be realized.
